2.8. Apply a muscle noise filter
Muscle noise in an ECG signal hides low amplitude signals that may be important for the
interpretation of an ECG. You can remove this noise with a muscle noise filter.
To apply a muscle noise filter:
At the top of the Real-time monitor, click Muscle filter. Click again to switch the filter off.
2.9. Record an ECG
You are now ready to record the ECG.
To record an ECG:
1. In the Real-time monitor wait until the signal is stabilized and click the Record button to
start recording. The progress of the recording is shown in the gauge at the bottom of the
window.
2. Next see §2.1follow steps 8-9.
Create a pretriggered recording
When you want to catch a particular event, such as arrhythmia, without having to record an entire
ECG, you can use a pretriggered recording. When you start a pretriggered recording, it includes
the five seconds before and after you clicked on the Record button. This means that when you
see an event and click the Record button, your recording includes the event, five seconds before
the event, and five seconds after the event.
The pretriggered option is also convenient when you have difficulties recording an ECG with
clean traces, for example because the patient has muscle spasms. The pretrigger option helps
defining the 10 seconds of recording by already saving 5 seconds of possibly clean traces.
To create a pretriggered recording:
1. Create a new test and switch on the MD or Portable recorder, the Pro is switched on
automatically. The Real-time monitor is displayed.
2. In the Real-time monitor, click the Pretrigger option.
3. Wait until you see the event that you want to record.
4. As soon as you see the event, click the Record button. Welch Allyn CardioPerfect will
continue recording for five more seconds.
5. Next see §2.1 follow steps 8-9.
6. The recorded ECG is automatically displayed, including the event that you wanted to
capture.
